Use the <dvt:graph> tag to create an ADF data visualization graph. Since it is very complex and difficult to use most consumers will want to use the simple graph tags that are supported in UI.

The <dvt:graph> tag gives you the capability of producing more than 50 types of graphs, including a variety of bar graphs, pie graphs, line graphs, scatter graphs, and stock graphs. Even though some graph attributes and some graph child tags are meaningful for only certain graph types, the graph tag has a complete set of graph attributes and supports the use of all graph child tags. One of the most commonly useful child tags is the <dvt:series> tag. A series appears as a set of markers that are of the same color. Use a set of <dvt:series> tags, within a <dvt:seriesSet> tag, to change bar or line colors, for instance. Bars in a Bar graph, datalines in a Line graph, and slices in a Pie graph, for instance, all use the series attribute "color" to define color.

The Graph's layout is dominated by five major components: title, subtitle, footnote, legendArea, and plotArea. The plotArea plots the data and is always rendered, but the other four components are optional, and can be placed in different locations within the graph. Within the area allocated to the whole graph, space is first allocated to the titles, if present. The title and the subtitle are displayed side by side at the top of the graph by default, and the footnote is displayed at the bottom of the graph. Space is next allocated for the legendArea, which displays the marker color and label associated with each series. It can be positioned in one of four locations: left, right, top and bottom. The legend can use as much as 40% of the graph space. The plotArea and its labels occupy the remaining space.

Data Model

Use the data binding dialogs to bind the simple graph tags to a data control, which is typically based on a rowset (see data binding documentation for details). Another common way to provide data for the graph is to use the "tabularData" attribute to create a grid. This requires use of a backing or managed bean.

The graph requires a simple grid of numeric data points to plot a graph. The grid's row and column labels are used to identify components within the graph, depending on graph type. By default, the rows appear as the series and the columns appear as the groups. A series is always a single row of data but a group can be collection of one or more columns. Every graph type may have a different requirement for minimal number of series and/or groups. For example, a Line graph requires at least two groups (group being a single column in this case) of data because a line segment requires at least two points to define it. Area graphs have the same requirement, being lines with the area underneath them filled in. The data is represented by a location on a Scatter or a Polar graph, hence these graph types require two columns per group. Bubble graphs need size of the data markers in addition to the location and require three columns per group. Pareto graphs display bars and a line that indicates the cumulative percentage of the bars. This graph type requires only a single series of data and uses one column per group. This graph type does not display a legend. Various Stock graph subtypes require different numbers of columns per group. See Data Model for <dvt:stockGraph> for details. A Pie graph displays one group of data, each slice representing a different series. This graph type requires one column in the grid, with multiple rows, one for each slice. Multiple Pie graphs show one pie for each group, or column, of data. Pie and Bar graphs can be drawn with just one data point, though such graphs may not be useful. Funnel graphs do not use the series concept, but generally require two rows of data. The first row provides actual data values, and the second row provides target values. Funnel graph legends display threshold values.

Series

The rows in the grid usually appear as the series in a graph. In most graphs, a series appears as a set of markers that are the same color and or the same shape, for instance. The graph legend typically identifies each series in the graph, with a labeled symbol that shows color and other appropriate attributes. Use a set of <dvt:series> tags, within a <dvt:seriesSet> tag, to change bar or line colors, for instance. Bars in a Bar graph, datalines in a Line graph, and slices in a Pie graph, for instance, all use the series attribute "color" to define color. The <dvt:seriesSet> tag contains attributes that change the default attributes for all series. The <dvt:seriesSet> tag also contains the <dvt:series> tags that override attributes for individual series. Commonly used series attributes are - color, lineWidth (change dataline width on a Line graph), marker type (change Marker to either bar, line, or area on a Combination graph), assignedToY2 (change axis assignment on a Dual-Y graph), pieSliceExplode (separate a slice away from the rest of a Pie graph), etc.

Here is an example of a Line graph with a <dvt:seriesSet> tag that defines a line width and a marker shape for all series. The <dvt:series> child tag overrides both lineWidth and markerShape for the first series in the graph. -

SeriesEffect

Use the graph's "seriesEffect" attribute to add predefined gradient effects on series related components such as bars, areas, and slices.

Series highlighting

Use the graph's "seriesRolloverBehavior" attribute to turn on highlighting behavior when the cursor moves over a series marker or a series-specific legend component. Note that seriesRolloverBehavior is not supported for funnel graphs.

MarkerText

The markerText tag defines if and where the marker text should appear in relation to series markers. Use the attribute "markerTextPlace" to specify the location of the text.

Titles

The title and the subtitle, if present, are displayed side by side at the top of the graph by default. Use the graph's "customLayout" attribute to change this default setting. The footnote, if present, is displayed at the bottom of the graph.

Legend

The legend displays the marker and associated color of each series. It also displays the legend title and lists any reference objects that are present. The legend can be positioned in one of four different locations: left, right, top and bottom. Use the attribute "alongGraphEdge" to attach it to the edge of the graph. The legend can be removed with the "rendered" attribute. The legend is never displayed for graph types that require only one series of data: Pareto and Candle Stock graphs. The legend doesn't always display the series components; showing threshold values for the Funnel graph, for instance.

PlotArea and Axes

All graph types except Pie and Funnel plot the data within the plotArea. Pie and Funnel graphs use pieFrame and funnelFrame, respectively, instead. The plotArea integrates the axes and the data markers. Generally the horizontal axis can be either an ordinal/category axis (o1Axis) or a data axis (x1Axis). Graph types such as Bar, Line, Area, Pareto, Pie, and Stock use the o1Axis, which shows categories like cities or products. Graph types such as Scatter, Bubble, and Polar use the x1Axis, which show numbers. The x1Axis can be a time axis if a Line or an Area graph is displaying dates (instance of java.util.Date). The primary vertical axis is a data axis (y1Axis). Dual-Y graphs typically also display the y2Axis. Each axis, whether ordinal or data, has tick labels and an axis title associated with it. The y1Axis is associated with y1TickLabel and y1Title, for instance. See related component tags for detail.

Number Formatting

DVT graph supports number formatting on its X1, Y1 and Y2 axis tick labels as well as for marker text that appear on the data markers. Users can customize the number formatting by adding <af:convertNumber> to the <dvt:x1TickLabel>, <dvt:y1TickLabel>, <dvt:y2TickLabel>, <dvt:x1Format>, <dvt:y1Format>, and <dvt:y2Format> tags. The following is an example of how to configure these tags:

Graph automatically determines the scale ( e.g. 4K ) and precision ( e.g. show 2 decimal points - 0.25 ) based on the values that are being displayed. This automatic formatting still occurs when <af:convertNumber> is specified. The graph tags that support <af:convertNumber> child tags ( e.g. <dvt:y1TickLabel>, <dvt:y1Format>, ...) also have scaling and autoPrecision attributes that can be used to control graph's automatic number formatting. By default, scaling="auto" means graph will auto-calculate the scale. For example, 40,000 will be formatted as "40K". By default, autoPrecision="on" means that graph will auto-calculate the precision of the number. For example, 0.230546 will be displayed as "0.23". If the autoPrecision is 'on' then all of the <af:convertNumber> fraction digit settings ( e.g. min/maxFractionDigits or pattern) are ignored.

Formatting Percent Graphs

Percent graphs require special formatting, since internally the graph calculates percent values, which can be displayed as numbers (e.g. 0.25) or percent (e.g. 25%):

Formatting Percent Axis - when <af:convertNumber> is added to the <dvt:y1TickLabel>, the values will be displayed based on what format is specified. For example, if the convertNumber type is number then the values are formatted as numbers (e.g. 0, 0.1, 0.2, etc.). However, if the convertNumber type is percent then the values are formatted as percent (e.g. 0%, 10%, 20%, etc.). Please note that if <af:convertNumber> is not added to the <dvt:y1TickLabel> then the graph will format the values as percent. To achieve the same format using <af:convertNumber>, <af:convertNumber type="percent"> must be used.

Formatting Marker Text / Marker Tooltips - On percent graphs, marker text is always displayed in a percent format and optionally, marker tooltips can either display values as percent or numbers. When displaying percents in marker text or when the markerText tooltip type is set to percent (valid value are MTT_PERCENT_VAL, MTT_PERCENT_VAL_TEXT, MTT_PERCENT_VAL_VALUES and MTT_PERCENT_VAL_VALUES_TEXT), the formatting engine will use the markerText format and will automatically force the convertNumber type to percent. When <af:convertNumber> is forced to percent, graph clears <af:convertNumber> pattern, since the pattern will prevent type=percent if specified. This means that patterns are ignored when graph forces percent formatting.

Categorical attributes formatting

Graph typically uses categorical attributes ( e.g. product, geography, year, etc. ) on an ordinal axis and for the marker tooltips. To specify how categorical attributes should be formatted, an application needs to specify <dvt:attributeFormat> tag for each categorical attribute to be formatted. The <dvt:attributeFormat> tag needs to identify the categorical attribute that is being formatted by name as well as specify a converter to use when formatting the attribute. For example,

The name of the categorical attribute is the name of the attribute/layer that was added to the Graph DataModel. The Graph model can be set declaratively by updating the pagedef. Here is the associated view pagedef for the above graph:

If there is a single categorical Date attribute being displayed on the O1Axis, then Graph displays a TimeAxis instead of the typical O1 / Ordinal Axis. The TimeAxis will show dates in a hierarchical format as opposed to as a single label on an O1 Axis ( e.g. June 27, 2001 ). To show a single label on the O1 Axis, the TimeAxis should be turned off ( e.g. timeAxisType="TAT_OFF" ) and a <dvt:attributeFormat> should be used to specify the date format.

Time Axis

The graph displays a time axis when dates (object type java.util.Date) are specified for the column labels in a Line or Area graph. Several timeXXX attributes are defined on the graph tag to customize the time axis. The child tag timeAxisDateFormat controls the format in which the time axis labels are displayed.

Time Selector

Use the <dvt:timeSelector> tag to activate the graph's TimeSelector feature, which allows an end user to select a time range on a time axis. This is typically used in master-detail graphs where the selected time range in the master graph drives the content of a detail graph, table, or other component. A backing or managed bean is required to use this feature.

Graph Size

The default graph size is 300 pixels tall by 400 pixels wide. Change this using the "inlineStyle" attribute. Set inlineStyle="width:500px; height:350px;", for instance, to change the graph size to 350 pixels tall by 500 pixels wide. The width and the height can also be specified in percent. Use percent for height only when the graph is added to an explicitly sized container or one that manages layout, otherwise graph will behave differently for different browsers. Use the "dynamicResize" attribute to resize the graph based on its container size.

Animation

Several graph types support animation. Animate the graph during initial rendering using the attribute "animationOnDisplay". The graph can also be animated when the data changes using the attribute "animationOnDataChange". Use the attribute "animationDuration" to specify the animation duration. The indicator colors for increase and decrease in the data value are specified by attributes "animationUpColor" and "animationDownColor", respectively.

Alerts

Use a <dvt:alert> tag for the graph to define an additional data point that needs to be highlighted with a separate symbol, such as for an error or warning. Wrap all <dvt:alert> tags in a <dvt:alertSet> tag.

Annotations

ReferenceObject

Use the <dvt:referenceObject> tag to create either a reference line or a reference area. The reference object can be associated with any data axis or series. Multiple reference objects can be associated with a single series or an axis. Use the attribute "location" to specify whether the referenceObject should displayed in the front or the back of the data markers. Use graph's "referenceObjectDisplay" attributes to specify when the referenceObject would be displayed: the value "RO_AUTOMATIC" displays it only when the mouse hovers over the component with which the referenceObject is defined. Wrap all <dvt:referenceObject> tags in a <dvt:referenceObjectSet> tag.

Interactivity

Use the shapeAttributes tag to specify interactivity on an individual graph component. A backing or managed bean is required to use this feature.

Here is an example of a dataline in a line graph using a clickListener to display series information:

Tooltips

Tooltips are useful to display identification and or detail information for data markers. They can be very useful in smaller graphs without enough space to display markerText. Use attributes "markerTooltipType", "seriesTooltipLabelType", and "groupTooltipLabelType" to customize tooltip content. The graph automatically displays tooltips for components like title, subtitle, footnote, legendText, and annotations when their text is truncated. There is no option to change this behavior.

Zoom and Scroll

Give end users the ability to zoom in on and scroll through a data set that may be too large or complex to fit comfortably within the area allocated to the graph using the "zoomDirection" attribute. Zoom and scroll may be enabled for horizontal and or vertical axes. The "scrollbarPresenceGroups" attribute provides control over when a scroll bar appears for the group axis: the horizontal axis in Line graphs, for instance. The "scrollbarPresenceX1", "scrollbarPresenceY1", and "scrollbarPresenceY2" attributes control the appearance of scroll bars for the various data axes.

Font

The <dvt:graphFont> tag is used for font formatting. Text color, style, size, and font name can be specified using this tag. This tag is used as a child tag for any of the graph's text component tags. All text component tags have other formatting attributes like horizontal and vertical alignment, text string, and whether or not the text should be rendered.

SpecialEffects

Use the <dvt:specialEffects> tag to specify gradient effects on many graph subcomponents. This tag must be defined as a child tag of the component tag and is not available for any text components. Note that the "seriesEffect" attribute setting always overrides the special effects settings.

Removal of an existing component

At design time JDeveloper automatically generates a bunch of child tags for the graph. These tags are added for convenience. Removing these tags will not hide the components themselves. To physically remove an existing component from the graph, use the attribute "rendered" to "false".

In JDeveloper design time, a graph automatically generates the legend area by default <dvt:legendArea>. Here is an example to remove the legend area of a graph

Example

Here is an example of a <dvt:graph> tag used to create a vertical bar graph with 3D effect. Bars on the graph are displayed as cylinders. The graph uses the "inlineStyle" attribute to specify size. The legend is displayed at the bottom and an ordinal axis title is specified for added description.

Geometry Management

This component can be stretched by a parent layout component that stretches its children, e.g. panelStretchLayout, panelSplitter, if dynamicResize="DYNAMIC_SIZE" is set.

This component does stretch to fill up the browser's viewport when it is the "sole visual root component" in the component tree, if dynamicResize="DYNAMIC_SIZE" is set.

When NOT stretched, this component will be displayed in its default dimensions which are provided by the skin. This can be modified by applying a dimension using the inlineStyle or styleClass attributes.

String

Yes

Provides a declarative way to customize the tooltips that appear on the graph. By setting the markerTooltipTemplate attribute to a tokenized string, an application can quickly format all the marker tooltips. This feature is a more performant alternative to the customTooltipCallback, since tokens can be sent to the client instead of preconstructed tooltip strings. This reduces the graph payload significantly, especially for large datasets.

The markerTooltipTemplate attribute accepts a String that may contain any number of a set of predefined tokens. When the tooltips are generated, the tokens are replaced with the information corresponding to each marker. Valid tokens are:

The listener interface for receiving scroll events on the graph. The event triggers when an axis of a graph is scrolled. Here is an example of scrollListener implementation that displays the range of the Y1 Axis and the O1 Axis -

Determines the series effect that is used for a graph. Valid values are:

SE_NONE - No series effect is used for the graph. This value causes markers to appear flat and sets the graphicAntialiasing attribute to "false".

SE_GRADIENT - Sets a special gradient on data markers to make them look more polished and sets graphicAntialiasing to "true".

SE_AUTO_GRADIENT - (Default) Works similar to SE_GRADIENT except in the case of a large dataset. If the graph displays a large dataset, then the gradient is not displayed in data markers so that peformance is improved.

Series 6 will display the same color as series 2
Series 7 will display the same color as series 3, and so on.

Deprecated. Use dvt:referenceObjectSet tag and its displaySeries attribute instead. Controls whether reference lines related to a series should be displayed when the mouse hovers over a data series. Valid values are the following:

RO_DISPLAY_NEVER - Does not display reference lines for a data series.

Specifies series information in a tooltip. Valid values are as follows:

TLT_NONE - Displays no series information

TLT_MEMBER - (Default) Displays the member label of the series in a tooltip

TLT_DIM_MEMBER - Displays the dimension member label of a series in a tooltip

Note: The graph displays series tooltip labels only if markerTooltipType is set to a value that includes text.

shortDesc

String

Green when the data value is less than 1000.

Yellow when the data value is less than 40.

Red when the data value is less than 20.

The following example refers to a style rule bundle called myRuleBundle that is stored in the backing bean SampleGraph: styleRuleBundle="#{sampleGraph.myRuleBundle}"

Indicates whether fonts should be embedded directly in the generated SVG. This attribute offers one way to avoid inconsistencies between fonts available on the middle tier and fonts available on the client. Valid values are:

SVG_FONT_EMBEDDING_NONE - Do not embed fonts in the generated SVG.

SVG_FONT_EMBEDDING_ALL - (Default) Embed all fonts in the generated SVG. This option requires additional processing and significantly increases the size of the SVG file.

Note: SVG is only supported as a printing format, so this attribute should no longer be used.

tabularData

java.util.List

Yes

Specifies a list of data that the graph uses to create a grid and populate itself. The List consists of a three-member Object array for each data value to be passed to the graph. The members of each array must be organized as follows:

The first member (index 0) is the column label, in the grid, of the data value. This is generally a String. If the graph has a time axis, then this should be a Java Date. Column labels typically identify groups in the graph.

The second member (index 1) is the row label, in the grid, of the data value. This is generally a String. Row labels appear as series labels in the graph (usually in the legend).

The third member (index 2) is the data value, which is usually a Double.

textAntialiasing

boolean

Yes

Default Value: false

Indicates that the text in a graph should be smooth. The default value is false.

threeDEffect

boolean

Yes

Default Value: false

Indicates whether a graph appears to have depth. Valid values are "true" and "false" (Default).

public void timeAxisListener (TimeAxisEvent event){
Date date = new Date(event.getTime());
System.out.println("User clicked at "+date.toString()+" on the time axis.");
}

Indicates the type of time axis data and the expected behavior if requirements for a specific type are not met.

The following types of time axis data are supported:

Discrete - Observations are usually spaced at regular intervals.

Continuous - Observations occur at any instant of time. There are two types of continuous time axis data:

Irregular - Multiple series of data have observations at the same instants of time.

Mixed frequency - Each series has observations at different instants of time.

The constants that specify time axis type also indicate the expected behavior when the requirements for a particular time axis type are not met. The following kinds of behavior are possible:

Fallback position - For these constants, if the requirements for a time axis type are not met, then the graph degrades gracefully.

Strict position - For these constants (which are indicated by the suffix "_STRICT"), if the requrements for a particular time axis type are not met, then an error message is displayed and no fallback position is provided. To provide custom text for the error message, register oracle.dss.graph.DataErrorTextCallback with the UIGraph.

Valid values are as follows:

TAT_DEFAULT - (Default) Provides a discrete time axis for bar, line, area, combination, or stock graphs and for all their subtypes, if the following requirements are met: (1) Dates must be on the group edge and (2) dates must occur at regular intervals. The discrete time axis is plotted on the ordinal axis, which is also known as the O1-axis. This constant provides the following fallback position if requirements are not met: Time axis is disabled and all labels are converted to strings.

TAT_IRREGULAR - Provides a continuous time axis on the X-axis for bar, line, area, or combination graphs (only for subtypes dual-Y and split). Stacked graphs are not supported. Additional requirements are: (1) Dates must be on the group edge, (2) dates must occur at regular intervals (sorted or unsorted), and (3) Only one dimension (layer) can exist on the group edge, if the data is provided through DataAccess interface. This constant provides the following fallback position if requirements are not met: Dates (if present) are converted to strings, the time axis is disabled, and an AlertEvent is fired to all AlertListeners that are registered with the graph.

TAT_MIXED_FREQUENCY - Provides a continuous time axis on the X-axis for bar, line, area, combination, or scatter graphs for subtypes dual-Y and split. Stacked graphs are not allowed. Additional requirements are: (1) Data cells should contain dates, (2) the data to be plotted along the X-axis should be of type Date, and (3) the data to be plotted along the Y-axis must be a number.

TAT_DEFAULT_STRICT - Provides discrete time axis as described in TAT_DEFAULT except that no fallback position is available. If requirements are not met, then an error message is displayed.

TAT_IRREGULAR_STRICT - Provides continuous time axis as described in TAT_IRREGULAR except that no fallback position is available. If requirements are not met, then an error message is displayed.

TAT_MIXED_FREQUENCY_STRICT - Provides continuous time axis as described in TAT_MIXED_FREQUENCY except that no fallback position is available. If requirements are not met, then an error message is displayed.

TAT_OFF - Turns off the time axis.

timeRangeEnd

java.util.Date

Yes

Specifies explicit time range end date for the time axis. TimeRangeMode property must be set to TRM_EXPLICIT. Only EL is supported.

TRM_RELATIVE_LAST - Using relative time range from the last data point. The range can be set using the relativeTimeRange attribute. Suppose the time axis is showing Jan 2 - Jan 14 and we need only the LAST 7 days, then the following properties must be set: relativeTimeRange = (7 days in milliseconds).

TRM_RELATIVE_FIRST - The usage is similar to TRM_RELATIVE_LAST. Using relative time range from the first data point. The range can be set using the relativeTimeRange attribute. Suppose the time axis is showing Jan 2 - Jan 14 and we need only the FIRST 7 days, then the following properties must be set: relativeTimeRange = (7 days in milliseconds).

TRM_EXPLICIT - Used for setting explicit time range. On a time axis, you can specify an explicit time range to show up on the time axis using the following attributes: timeRangeStart and timeRangeEnd.

Also see the following related properties: relativeTimeRange, timeRangeStart, and timeRangeEnd.

timeRangeStart

java.util.Date

Yes

Specifies explicit time range start date for the time axis. TimeRangeMode property must be set to TRM_EXPLICIT. Only EL is supported.

timeRelativeRange

long

Yes

Specifies relative time range(in milliseconds) from the last data point or from the first data point on the time axis. timeRangeMode must be set to TRM_RELATIVE_LAST or TRM_RELATIVE_FIRST. Only EL is supported.

timeSelectorListener

javax.el.MethodExpression

Only EL

Deprecated. Use dvt:timeSelector tag and its timeSelectorListener attribute. The listener interface for receiving time selector events on the graph. The TimeSelectorEvent contains information about the new extents of the time selector. Here is an example of timeSelectorListener implementation that displays the range of the time selector -

Specifies a method reference that returns an instance of java.util.TimeZone. The graph uses this time zone when it formats dates. The following example refers to the method myTimeZone in the SampleGraph backing bean: timeZone="#{sampleGraph.myTimeZone}"

tokenSubstitution

oracle.dss.dataView.TokenSubstitution

Yes

Defines methods that allow you to substitute text for a token in a String.

value

String

Yes

Specifies the graph's data model. This must be an instance of oracle.adf.view.faces.bi.model.DataModel or oracle.adf.view.faces.bi.model.GraphDataModel

visualEffects

int

Yes

Valid Values: NONE, AUTODefault Value: AUTO

Specifies the type or types of visualEffect to apply. Valid values are:

Deprecated. Use zoomListener and scrollListener attributes instead. The listener interface for receiving zoom and scroll events on the graph. The event triggers when an axis of a graph is zoomed and/or scrolled. Here is an example of zoomAndScrollListener implementation that displays the range of the Y1 Axis and the O1 Axis -

The listener interface for receiving zoom events on the graph. The event triggers when an axis of a graph is zoomed. Here is an example of zoomListener implementation that displays the range of the Y1 Axis and the O1 Axis -
